5/14/2010 5:36:53 AM BOINC can't access Internet - check network connection or proxy configuration.
I keep getting this error message and don't know what to do about it. My work units are piling up and they are not being sent. can someone guide me through the process. I have rebooted but still not uploading completed units. I am connected to the internet via cable and am always on.

Despite Seti having a problem with their upload server, this doesn't account for your BOINC claiming you have no internet connection.

You do have an internet connection, else you couldn't post on the forums, but BOINC just can't find it. That's usually the case when it's blocked. So check that BOINC is being allowed (still) through your firewall (boinc.exe needs access to internet on TCP ports 80 and 443). It happens that OS updates do weird things with the firewall software.

It has nothing to do with the project being down, one of the servers being down etc. It is caused by something blocking BOINC getting access to the internet.
What causes BOINC to be blocked from getting access to the internet? Firewalls, proxies, no internet.

Ok one problem solved, a security update for Windows Defender was keeping my computer from communicating with BOINC. I like to keep my computer up to date with security updates installed. If I reinstall this update for defender where do I go to make the necessay changes with my computer settings so that defender allows communications with BOINC. I'm running Vista 64 and my security settings are all at default level.

From what I could fine out Window firewall comes with Vista when SP2 is installed. It is a part of Windows defender. Appearantly when I installed the security update to Windows defender it effected the firewall part of the program. At least that is what I assume as the problems started right after the update and ended when I deinstalled it.

The firewall came turned on with Vista Beta 1, and has been defaulted on ever since.

Windows defender is supposed to be a separate program from Windows Firewall. However, you should check your firewall settings.

Windows 7 has a new firewall that may be included in Vista SP2 that does outbound as well as inbound rule checking. I have not looked ad the Vista SP2 firewall, so I really don't know if this is the case or not.
